Fe BPUR and other blood boys. My real question in this space is how do you ever run a good study? To be honest, I think the FDA has been bending over backwards to try and allow such studies, but it is still difficult. Who will consent to use a product that hopefully is a good as blood? Can somebody in an ambulance sign a consent form? I think there is a very real need for a product in this space (blood demographics at the least).
